In the spring of 1996, the Wheaton College Vernal Pool Research Team
began a long term study monitoring the Spotted Salamander (Ambystoma
maculatum) population breeding in Wheaton's certified vernal pool.
Between March 16 and May 2, the Research Team caught, documented, and released
41 individual salamanders using a drift fence and pitfall trap system.
Data were collected on the length, weight, genital pore width, and sex
of each individual salamander. "Catalogues" composed of photographs
and drawings of each salamander's unique spot pattern were compiled, which
allow for later identification of previously captured salamanders. Additionally,
a record was kept of the rates at which salamanders were captured and recaptured.
The Research Team continued monitoring efforts the following spring using
refined methods. Between March 27 and May 16, 1997, 46 salamanders were
captured for the first time and 7 slamanders were recaptured. In the two
years, the Research Team has begun to build a foundation of data with which
to do multiple-year studies of population dynamics within Wheaton's vernal
pool salamander population. Population estimation and weight comparison
studies using the data have already provided initial results with which
to shape future studies of A. maculatum.
